Struct ValidatedAlphabet 

pub struct ValidatedAlphabet { /* private fields */ }

An owned, immutable, validated 64-byte Base64 alphabet.

Encode and decode mappings are both derived from table. The type has no executable callback or overridable mapping method.

Implementations

impl ValidatedAlphabet

pub const fn new(table: [u8; 64]) -> Result<Self, ValidatedAlphabetError>

Validates and owns a 64-byte alphabet.

pub const fn try_from_slice( bytes: &[u8], ) -> Result<Self, ValidatedAlphabetError>

Copies, validates, and owns a 64-byte alphabet slice.

pub const fn as_array(&self) -> &[u8; 64]

Returns the single table that defines both mappings.

pub const fn encode_value(&self, value: u8) -> Option<u8>

Returns the encoded symbol for one six-bit value.

pub const fn decode_byte(&self, byte: u8) -> Option<u8>

Returns the six-bit value represented by byte.
